Description

Technical Field

[0001] The invention relates to the technical field of insulated busbar bending pipes, and in particular to an EPDM insulated busbar bending pipe device and method. Background Art

[0002] The bent pipe is bent using a complete set of bending equipment. The EPDM insulated busbar needs to be bent using bending equipment during the processing process so that it can be suitable for different working environments.

[0003] When the existing EPDM insulated busbar bending equipment is performing the pipe bending operation on the EPDM insulated busbar, the EPDM insulated busbar is placed at a specified position and then bent directly by the pipe bending equipment. During the pipe bending process, both the inside and outside of the bending position will be deformed to a large extent. This deformation will cause the inner diameter of the EPDM insulated busbar at the bending position to be smaller than the diameter at the normal position, which will affect its use value to a certain extent. Therefore, the modified pipe bending equipment has certain defects. Summary of the invention

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] The EPDM insulated busbar bending device disclosed in the present invention is mainly used for existing EPDM insulated busbar bending devices. When the EPDM insulated busbar is bent, the EPDM insulated busbar is placed at a specified position and then bent directly by the bending device. During the bending process, both the inside and outside of the bent position will be deformed to a large extent. This deformation will cause the inner diameter of the EPDM insulated busbar at the bent position to be smaller than the diameter at the normal position, affecting its use value to a certain extent.

[0037] Reference Figure 1-Figure 11A EPDM insulated busbar bending device comprises a processing table 1, a bending die 10 and a matching die 4, a positioning clamping assembly 8 is provided on one side of the matching die 4, and an inner support assembly 9 is provided at the positioning clamping assembly 8, the inner support assembly 9 comprises two end assembly plates 901, and the opposite sides of the two end assembly plates 901 are fixedly connected with intermediate shafts 911, the two intermediate shafts 911 are connected by hinges, and the outer sides of the intersection of the two intermediate shafts 911 are fixedly connected with the same intermediate extrusion airbag 902, and the intermediate extrusion airbag An air hole is opened on one side of 902, and an air pipe 908 is fixedly connected to the inside of the air hole. The outer wall of the air pipe 908 is connected to the air valve 904 through a flange. Two intermediate shafts 911 are located on the outer walls of both ends of the middle extrusion airbag 902, and are evenly fixedly connected to electric telescopic rods 905. The output ends of the multiple electric telescopic rods 905 located on the same intermediate shaft 911 are fixedly connected to the same extrusion ring frame 907. The extrusion ring frame 907 is evenly fixedly connected to a rear baffle 906 on one side away from the middle extrusion airbag 902.

[0038] In a specific application scenario, when performing the EPDM insulated busbar bending operation, the internal support assembly 9 is moved to the EPDM insulated busbar bending position, and as the driving motor 11 drives the bending mold 10 to rotate, one of the intermediate shafts 911 begins to deflect. During the deflection, the electric telescopic rod 905 is adjusted to drive the extrusion ring frame 907 to extrude toward the intersection of the two intermediate shafts 911, and the middle extrusion airbag 902 is squeezed at both ends through the extrusion ring frame 907, so that the gas at the center position of the middle extrusion airbag 902 moves toward the periphery, thereby increasing the internal support force at the periphery of the middle extrusion airbag 902, and the EPDM insulated busbar bending position is supported by the internal support force to avoid large deformation at the bending position, improve the bending effect, and thus improve the use value of the bending equipment.

[0039] Specifically, when the extrusion ring frame 907 is pushed, the rear baffles 906 behind it partially block the gas squeezed toward the two ends by the middle extrusion airbag 902, on the one hand to prevent the middle extrusion airbag 902 from being damaged due to excessive force and internal pressure at the periphery, and on the other hand to prevent the gas inside the middle extrusion airbag 902 from flowing too much toward the two ends, so that it is mainly concentrated at the bend.

[0040] It should be noted that when the EPDM insulated busbar is bent, large vibrations will be generated. The inner support fitting plate 903 here is connected to the assembly bracket 909 through the bracket 910, so that the shock-absorbing spring rod 912 is in a compressed state. The shock-absorbing spring rod 912 in the compressed state weakens the vibration generated during the bending process, thereby reducing the impact of the vibration on the EPDM insulated busbar and avoiding the deviation of the bending position due to the vibration.

[0041] Reference Figure 1-Figure 5 In a preferred embodiment, the outer side walls of the two intermediate shafts 911 are provided with multiple groups of shock-absorbing spring rods 912, and the ends of each group of shock-absorbing spring rods 912 are fixedly connected to an inner support fitting plate 903, and each inner support fitting plate 903 is fixedly connected to a bracket 910 on the arc surface facing the intermediate shaft 911, and the outer side wall of the intermediate shaft 911 close to the bracket 910 is fixedly connected to an assembly bracket 909, and the assembly bracket 909 is plugged into the bracket 910, and multiple inner support fitting plates 903 located at the periphery of the same intermediate shaft 911 form a circular frame.

During the extrusion process, the clamping plate 805 gradually fits with the outer wall of the insulating busbar to complete the clamping. When the insulating busbar continues to advance, the telescopic connecting rod 802 is stretched, and the fixed frame 803 at the end of the insulating busbar moves accordingly. After the insulating busbar moves to the specified position, the hydraulic cylinder three 804 on the fixed frame 803 located at the periphery of the matching mold 4 adjusts the positioning frame 806 to extrude toward the insulating busbar to complete the secondary positioning and clamping. In this way, the positioning and clamping of the insulating busbar is achieved, the stability of the insulating busbar during the bending process is improved, the deviation of the insulating busbar during the bending process is further avoided, and the accuracy of the bending position is improved.

[0044] It should be noted that after the clamping plate 805 is attached to the outer wall of the insulating busbar, the extrusion spring rod 807 is in a compressed state, and the extrusion spring rod 807 drives the clamping plate 805 to perform secondary extrusion and clamping on the insulating busbar. At the same time, the extrusion spring rod 807 in the compressed state realizes secondary shock absorption.
